The Mule is an interesting animal, they are the result of the mating of a male donkey and a female horse. Mules are unable to breed due to an uneven chromosome count. They are often bred to be used as riding and pack animals, as well as ploughing or any other work one might do with horses. A mule's body type and temperament depend on the breed of mare and jack used. Huge draft horses are prefered as they create multes that tolerate heat and require less feed.
